The windowsl are movable for.- 35a wardly along their guideways to. expose the Window opening. so that the .engineer may lean out of the opening to View the, track and to observe signals. The cab is provided with the usual outwardly projecting padded arm. rest 2| extending 40m along. the bottomedgeof the window opening. i f

AThe cab window opening I6 is made rather large;y not only to provide good visibility but also to form an emergency exit for the engine crea/so that' they may quickly escape from the 4,5l cabin case of necessity. For example, the cab of'. a4 steam locomotive vmay become .lled with live.l steam, as by. the breaking' of a gage glass.

If the windowslfland |.8 happen,v to be in closed' position.duringsuch accident they can be slid 50.. quickly to their open position. Y y

In aY cab window .structure of conventional type the inner slidaole window is like the Outer' window ll'. These windows are. closed in severe weathen. but beoauseot poor visibility it is usuoo. ally necessary t0. open them at intervals to per- Theopening is adapted to loey mit the engineer to project his head outwardly through the window opening and thus improve his View. Such exposure, however, may cause considerable physical discomfort and pain.

In accordance with the present invention, the conventional plain inner window is replaced by the window I8, which is extensible from the side of the cab and which will permit the engineer to project his head outwardly beyond the plane of the cab wall so as to have an unobstructed view, the window forming a shield or protector for the engineer. This window is further arranged to permit quick and easy retraction for avoiding damage by obstacles near the track and for allowing the window to be slid quickly to open position, so as not to interfere with theuse of the Window opening as an emergency exit.

The window I8 of the present invention includes a rectangular frame which is slidable in the guideways 20 and is here shown to consist of an outer frame member 22 and an inner frame member 23 detachably secured together, the inner frame member denning an opening`24 between its -side uprights or stiles. The frame may be constructed of wood or metal, or both of these materials, and in many instances the outer frame member may be of wood so as to permit easy trim# ming `to fit the cab guideways 2l), especially in cases where it is desired to apply the window to an existing locomotive. As shown in detail in Fig. 13, the outer frame member 22` of the rectangular frame has side rails or uprights 22a and top and bottom rails 22h, and the inner frame member 23 has side rails or uprights 23a and top and bottom rails 2317.

An articulated multipleV section sash assembly, comprising a series of pivotally connected glazed sash members or panels 25, 26, 21 and 28, is arranged to close the opening 24 in the frame member 23. The end sash member 25 is secured at its front edge to the front upright of the inner frame member 23 by a vertical hinge 29, andat its rear edge is secured to the front edge of the intermediate or side sash member 26 by a vertical hinge 30. The rear edge of the intermediate sash member 26 is secured to the adjacent edge of the rear sash member 21 by a vertical hinge 3|, and the two rear sash members 21y and 28 are connected by a vertical hinge 32. The rear edge of the end sash member 28 is connected to the rear upright of the frame member 23 by a vertical Y hinge 33 which is preferably a double hinge having an intermediate leaf 34. The intermediate or side sash member `26 is here shown to be considerably wider than the front sash member 25, and the two connected rear sash members 21 and 28, which are relatively narrow, have a cornbined width'about equal to the width of thejfront sashmember. Suitable handles 35 are secured to the inner side of some yof the sash members to facilitate the folding and Yunfolding of these members. These handles are here shown to be secured to the front uprights of the sash members 26 and 28. The combined width of the sash members 25 and 26 is about equal to the Width of the frame opening 24, and in the closed position of the' foldable-window, shown in Figs. 3 and 6, the

connected sash members 25 and 26 are in alignment in the plane of the frame 22, 23, and close the frame opening`24, permitting the frame to slide along the guideways 20 in the manner of a conventional plain window, so as to expose the window opening I6 in the cab side Wall. In the foldedposition of the articulated sash assembly, the narrow rear' sash members 21 and 28 lie at Y of the sash assembly the sash member 26 extends approximately parallel to the plane of the cab wall and is spaced outwardly beyond the arm .rest 2l, and the front sash member 25 and the lportion of the outwardly projected sash assembly, as seen in Figs. 2 and v5. The inner panel section 31 is pivotally secured to the horizontal bottom-rail of the windowframe member 23 by a hinge 39 having an L-shaped hinge leaf attached to this frame member, the` hinge axis extending parallel to this rail andV being spaced inwardly from the inner face of the frame member. The two sections of the bottom -panel vare connected by a hinge 40 extending parallel to the mounting hinge 39. In itsshelf-forming position the articulated bottom panel is suitably supported by the lower edge portions of one or more of the sash members 25, 26, and 28, 'as by inner ledgeforming ribs 4I on thesev sash members. When the bottom panel is in its shelf-forming position,

the articulated sash assembly is held in its extended position, forming a bay window, as seen in Fig. 2, land cannot collapse. In the retracted position of Athebottom panel, seen in Fig. 6, the panel sectionv 31 hangs below the hinge 38 and the panel section 38 is folded upwardly adjacent to its companionsection and is suitably held in place as by a friction catch 42. If desired, the panel section 38 may merely hang below the section 31', as shown by dotted lines in Fig. 6. A suitable handle 43 is secured .to the panel section 38 tof facilitate themanipulation of the bottom panel. f

An articulated top` panel 44, 45, generally similar to the bottom paneLforms a coveror roof for v the outwardly projected sash assembly, the inner panel section 44 being pivotally secured to the horizontal top rail of the window frame member 23 by a mounting hinge 46" similar to the bottom panel mounting hinge 39, and the two Vpanel sections 44 and 45 being connected by a hinge 41. The front, outer and rear edges"v of the top panel are provided withsealing strips 48 of rubber or other suitable resilient material having a frictional sealing engagement with the inner side walls of the severalsash members. These Sealing strips serve to exclude the weather-and also hold the top panel in its extended position. Preferably, spaced ribs or beads 49'are secured along the inner walls of one'ormore of the sash mem-- bers near their upper edges to form a shallow channel or seat for receiving the sealing strips. In some instances, the sealing strips may be secured to the sash members instead of to the top panel.

In the retracted position of the top panel, seen members in their closed or retracted position. The, mounting hinge 239 for the bottom panel is suitably recessed to admit the bolt of the latch.

The latch |53 may be used on either form of window.

,Certain speciiic embodiments of the invention have been shown and described, but it will be understood that changes and modifications may be made therein within the spirit of the invention.
